What are the reasons for the Volkswagen Tayron's brake pedal being hard to press?
1 Answers
Volkswagen Tayron's brake pedal being hard to press may be due to vacuum booster pump leakage or failure, lack of necessary maintenance of the brake system, excessive impurities in the brake master cylinder, and other reasons. The specific reasons are as follows: Vacuum booster pump leakage or failure: The force applied to the brake pedal is amplified by the brake booster pump. If it fails, the brake loses its main force, making it difficult to press down. Brake booster pump: The brake booster pump continuously generates vacuum only when the engine is running. When the engine is not running, it relies on the remaining vacuum assistance, which typically depletes after a few presses. However, this condition will recover after starting and is not a fault. Lack of necessary maintenance of the brake system: Excessive impurities in the brake master cylinder, poor sealing, vacuum booster pump failure, excessively dirty brake fluid or mixed brake fluids causing vapor lock when heated, leakage in the brake master cylinder or wheel cylinders, or leakage in the air reservoir or pipeline connections.
